Week 9: CS 338 first week

 Discuss the process of solving the Coding Bat challenges.  A major part of software design is thinking about how to approach a problem with the tools we have at our disposal.  What were the steps you took to solve some of these challenges? 

This week we worked on solving Coding Bat challenges. Some of them were very easy and I knew exactly how to solve these coding problems while a few were very difficult. One in particular I have not been able to finish it. For the more difficult coding problems I had to write out what I needed. I sat and worked on some pseudo code.  I also had to look up a lot of information since I it has been a few weeks that I had not written any serious Java. I had to get a refresher on a Java syntax, and library methods. I am working on this:

Return true if the given string contains an appearance of "xyz" where the xyz is not directly preceeded by a period (.). So "xxyz" counts but "x.xyz" does not.


xyzThere("abcxyz") → true
xyzThere("abc.xyz") → false
xyzThere("xyz.abc") → true

I got my code to pass all the test except one. I have worked on this for about 2 hours and I need to take a break. I think think sometimes its best to leave it alone for a little bit and come back with a refresh mind.

CST438 Software Engineering: Week 8 (Final week)

 One of the most important things I learned is that software engineering is about much more than just writing code. While coding is a big part, there's a strong emphasis on documentation, understanding client needs, and getting continuous feedback. It’s about designing systems so others can easily improve them and applying principles like "low coupling and high cohesion" to keep things modular and maintainable.      Another key lesson was understanding the entire development process from end to end. This was the first time I worked with both the front end and back end together, fully grasping the HTTP protocol (including how methods like POST work), how JSON is used, and how the front end communicates with the back end. Seeing how everything fits from database interactions to deploying the app online—gave me a fascinating glimpse into the full workflow and a lot of practical experience.      Another important lesson was learning how to work as part of ...

CST438 Software Engineering: Week 1

What did you expect a course in Software Engineering would cover? I expected it to cover how to build applications from the ground up and the design behind application development. I thought we would look at other things we’ve been learning in this program, like database management, front end development, and back end work, and then put it all together into one complete project. After completing week 1, how has your opinion changed? Well, I never really thought much about keeping an application’s design maintainable for future improvements or changes. There is a lot more that goes into software engineering than just simple programming. It is  about planning ahead, documenting your work, checking for errors, and testing properly to avoid issues later. I’ve also realized software engineering looks at the big picture it is not just about coding and design but about how software impacts people and how teams work together to build it. Developers need to stay motivated, think critical...

CST370 Week 5

Hello everyone,  This week we studied binary‑tree traversals preorder, inorder, and postorder but I kept mixing them up. I finally got it when I attended TA office hours, and it clicked. Walking through Quick Sort step by step helped me see how the Decrease and Conquer approach works by breaking problems into smaller chunks. Then we looked at Kahn’s algorithm, and watching it remove nodes with no incoming edges reminded me of picking a pivot in Quick Sort. Seeing these patterns repeat helped me realize that many algorithms work by simplifying things piece by piece.
